    Thanks Jerry.

    I am definitely not an expert but I can use a soldering iron and a tester.

    You referred to board swapping which doesn't tell me too much.

    If you explain me precisely what I have to do I can give a try and give you further information.

    Cheers

    Thanks a lot. Now it's a lot clearer.

    Anybody who could do that in my area (UK, postcode KT11...) for a reasonable price?

    Cheers

Most of the time, this is from a failed power supply board, and or a short on one of the other boards. Without board swapping this is a difficult thing to troubleshoot.

    There is no actual support by the manufactures for component level service in these sets. Even if I had a detailed service manual, I would not be able to determine the failed components unless I was to spend many hours troubleshooting the set using the proper diagnostics and instruntation. This would not be feasable by any means in comparision to exchanging complete boards. The circuit designs are extremely complex, and the are thousands of SMD type compenents involved.



    For soldering, you cannot go in with a standard soldering iron and change parts. The micro size SMD parts are changed using IR soldering systems that are very costly. Some of the pin spacings on some of the devices are closer than 1/50 of an inch apart and almost as find as a human hair.



    If you were able to determine the defective part, if the the part is not a generic type that can be bought at a regular electronics parts supplier, you would not be able to buy it from the manufacture since they do not support component level service. In many instances the specialized IC's require some software loading and parameter adjustment to adjust to the particular set.



    This is why the service reps are given boards for exchange from the manufacture. It is the same method as for servicing a computer but more involved.



    With board exchange, the set can usually be serviced within thirty minutes to one hour including calibration setups, unless there are some problems with the wiring harnesses, or something unexpected.

    You have to find out in your area who the authorized service people are for the TV manufacture. In the user instruction manual there are usually listings. I tried to find Bush using Google and Yahoo and came up with nothing in the way of support. You can ask the dealer where you bought the set.



    I have a feeling that this set may be a re-badged no-name brand set. There may not be any service support at all from what I can see. Here in Canada I have never seen this brand name.



    The corner service shops who are usualy independent, may not be able to have the spare boards for your set, or they may have to buy them to try them if they can source them. This will be more expensive than using the factory authorized service rep.



    I can tell you in advance that the boards for these TV sets are very expensive. In many cases it is actualy cheaper to replace the set rather than to service it.



    When you replace this TV set, make sure you buy a set that has local support and service. Stay with the big name brands that are well known. You may pay a little more, but it is worth the investment.

Need code for my remote control for my Bush Tv


Codes are in the remote. Finding the code depends upon knowing the "brand" of remote and whether it is universal (URC-???).

I have a Bush 31 inch smart tv and it switches itself on and off but when Its off red light keeps flashing and i cant use the remote please help im getting frustrated


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

I have a bush tv its got sound but no picture


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Tv has got stuck on standby mode


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
